A gigantic and resilient “cold front” hurtling through the Perseus galaxy cluster has been studied using data from NASA’s Chandra X-ray Observatory.

Astronomers using NASA’s Hubble Space Telescope have for the first time precisely measured the distance to one of the oldest objects in the universe, a collection of stars born shortly after the big bang. This new, refined distance yardstick provides an independent estimate for the age of the universe. The new measurement also will help astronomers improve models of stellar evolution. Star clusters are the key ingredient in stellar models because the stars in each grouping are at the same distance, have the same age, and have the same chemical composition. They therefore constitute a single stellar population to study.

NASA’s #StudentLaunch 2018 is today at Bragg Farms in Toney, Alabama. The Student Launch competition challenges middle school, high school and college teams to design, build and launch their rockets to an altitude of one mile. The competition is hosted by #NASAMarshall and encourages students in the STEM (science, technology, engineering, and math) fields.

This week in 1984, space shuttle Challenger, mission STS-41C, launched from NASA’s Kennedy Space Center. The primary mission objectives were to deploy the Long Duration Exposure Facility, an orbital facility designed to test the performance of spacecraft materials, components and systems exposed to the space environment, and to capture, repair and release the Solar Max satellite. This was the first on-orbit repair of a satellite. Here, crew members train for their repair tasks in NASA Marshall Space Flight Center's Neutral Buoyancy Simulator. The simulator prepared astronauts for extra-vehicular activities from its completion in 1968 until it was decommissioned in 1997.

Fifty years ago today, Apollo 6 launched from NASA’s Kennedy Space Center. The uncrewed Apollo 6 mission was the final qualification flight of the Saturn V launch vehicle and the Apollo spacecraft. The primary objectives of the mission were to demonstrate structural and thermal integrity and compatibility of the launch vehicle and spacecraft, confirm launch loads and dynamic characteristics, and verify stage separations, propulsion, guidance and control, electrical systems, emergency detection system, and mission support facilities and operations, including Command Module recovery. Pictured here is the Apollo 6 launch vehicle as it leaves Kennedy’s Vehicle Assembly Building on the transporter heading to launch pad 39-A.

More than halfway across the universe, an enormous blue star nicknamed Icarus is the farthest individual star ever seen. Normally, it would be much too faint to view, even with the world’s largest telescopes. But through a quirk of nature that tremendously amplifies the star’s feeble glow, astronomers using @NASAHubble were able to pinpoint this faraway star and set a new distance record. They also used Icarus to test one theory of dark matter, and to probe the make-up of a foreground galaxy cluster.

The star, harbored in a very distant spiral galaxy, is so far away that its light has taken 9 billion years to reach Earth. It appears to us as it did when the universe was about 30 percent of its current age.

Like a baby chick pecking its way out of an egg, the star in the center of the Egg Nebula is casting away shells of gas and dust as it slowly transforms itself into a white dwarf star. This photo, captured by @NASAHubble

This illustration shows #NASA’s Parker Solar Probe spacecraft approaching the Sun. The mission, launching in summer 2018, will revolutionize our understanding of the Sun, where changing conditions can spread out into the solar system, affecting #Earth and other worlds. The primary science goals for the mission are to trace how energy and heat move through the solar corona and to explore what accelerates the solar wind as well as solar energetic particles.
The spacecraft, about the size of a small car, will travel directly into the Sun's atmosphere about 4 million miles from the star's surface.

The exquisite sharpness of this 2005 image from @NASAHubble has plucked out an underlying population of infant stars embedded in the #nebula NGC 346 that are still forming from gravitationally collapsing gas clouds. They have not yet ignited their hydrogen fuel to sustain nuclear fusion. The smallest of these infant stars is only half the mass of our #Sun.

A new experiment facility, designed and built at NASA's Marshall Space Flight Center in Huntsville, Alabama, will be flown to @ISS in 2018. The primary focus of experiments in the new Life Sciences Glovebox will be to aid research on the long-term impact of microgravity on human physiology -- potentially leading to innovative techniques for protecting human explorers during bold new missions into deep space, and also improving life on Earth.

#NASA is busy outfitting the Space Launch System rocket with what it needs for Exploration Mission-1, the first integrated mission of #SLS and the #NASAOrion spacecraft. This picture shows platforms inside the launch vehicle stage adapter that will allow technicians at @NASAKennedy access to the stage while the rocket is on the launch pad. The adapter connects the rocket’s core stage with the interim cryogenic propulsion stage, which will fire its engine to send Orion into lunar orbit.
